Description

Technical Field

[0001] The invention relates to the technical field of tailings paste filling, and in particular to a tailings paste filling pipe lowering pressurizing device and method. Background Art

[0002] Mine paste filling technology is a technology that fills specific paste materials into the goaf during the mining process to improve the recovery rate of mineral resources and reduce environmental problems such as surface collapse. This technology can not only effectively support the ore body and prevent mining accidents, but also reduce the discharge of waste materials and achieve the purpose of environmental protection.

[0003] At present, in the process of vertically drilling holes on the ground to install filling pipes, when encountering underground faults, the borehole will be offset, which will cause the filling pipe to be offset when it is lowered. After the positioning steel casing arranged below and required to be plugged with the filling pipe is installed, it is difficult to plug the offset filling pipe into the positioning steel casing, thereby affecting the installation efficiency of the filling pipe. Summary of the invention

[0004] In view of this, the object of the present invention is to provide a tailings paste filling pipe lowering pressurizing device and method, so that the filling pipe can be smoothly inserted into the bottom positioning steel casing, thereby improving the installation efficiency of the filling pipe.

[0005] The present invention solves the above problems by the following technical means:

[0006] A tailings paste filling pipe lowering and pressurizing device comprises a clamp fixed to the filling pipe, a clamp pull plate stacked on the clamp, a pressure plate fixedly connected to a positioning steel casing, a movable pull plate slidably sleeved with the positioning steel casing, a jack arranged between the movable pull plate and the pressure plate, and a pull rod assembly for connecting the clamp pull plate and the movable pull plate.

[0007] Furthermore, the pull rod assembly includes a pull rod and a pull rod nut. The top and bottom ends of the pull rod pass through the clamp pull plate and the movable pull plate respectively. The top and bottom ends of the pull rod are threadedly connected with pull rod nuts. The pull rod nut at the top end is tightly attached to the top surface of the clamp pull plate, and the pull rod nut at the bottom end is tightly attached to the bottom of the movable pull plate.

[0008] Furthermore, a cushion block is provided between the pressure plate and the jack.

[0009] Furthermore, a fixture installation positioning block is provided on the filling tube.

[0010] Furthermore, the pressure plate is sleeved with the positioning steel sleeve and fixed by welding.

[0011] Furthermore, the pull rod passes through the pressure plate.

[0012] Furthermore, the clamp pull plate and the movable pull plate are connected via four sets of pull rod assemblies arranged at four corners.

[0013] Furthermore, jacks are provided on both sides of the positioning steel casing.

[0014] A method for lowering and pressurizing a tailings paste filling pipe adopts the above-mentioned tailings paste filling pipe lowering and pressurizing device.

[0015] Furthermore, the movable pull plate is pushed downward by the jack, and the movable pull plate drives the clamp pull plate to move downward through the pull rod assembly. The clamp pull plate pushes the clamp and the filling tube to move downward synchronously, thereby pressing the filling tube into the positioning steel casing.

[0016] Beneficial effects of the present invention:

[0017] The present invention provides a device and method for lowering and pressurizing a tailing paste filling pipe, the device comprising a clamp fixed to the filling pipe, a clamp pull plate stacked on the clamp, a pressure plate fixedly connected to a positioning steel casing, an active pull plate slidably sleeved and assembled with the positioning steel casing, a jack arranged between the active pull plate and the pressure plate, and a pull rod assembly for connecting the clamp pull plate and the active pull plate. The device and method of the present application can smoothly insert the filling pipe into the positioning steel casing at the bottom, effectively improving the installation efficiency of the filling pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings. Figure 1 As shown: On the one hand, this embodiment provides a tailings paste filling pipe lowering and pressurizing device, including a clamp clamped and fixed to the filling pipe, a clamp pull plate stacked on the clamp, a pressure plate fixedly connected to the positioning steel casing, a movable pull plate slidably sleeved with the positioning steel casing, a jack arranged between the movable pull plate and the pressure plate, and a pull rod assembly for connecting the clamp pull plate and the movable pull plate; in this embodiment, the pressure plate is sleeved with the positioning steel casing and fixed by welding.

[0021] The pull rod assembly includes a pull rod and a pull rod nut. The top and bottom ends of the pull rod pass through the clamp pull plate and the movable pull plate respectively. The top and bottom ends of the pull rod are threadedly connected with pull rod nuts. The top pull rod nut is tightly attached to the top surface of the clamp pull plate, and the bottom pull rod nut is tightly attached to the bottom of the movable pull plate. The pull rod passes through the pressure plate. Preferably, in order to improve the stability of the pulling process, the clamp pull plate and the movable pull plate are connected by four sets of pull rod assemblies arranged at the four corners; jacks are arranged on both sides of the positioning steel sleeve.

[0022] As a further improvement to the above technical solution, a cushion block is arranged between the pressure plate and the jack; the cushion block can transmit force evenly, so that the pressure plate is subjected to uniform force.

[0023] As a further improvement to the above technical solution, a clamp installation positioning block is provided on the filling tube; when the clamp is installed, the bottom of the clamp is positioned by the clamp installation positioning block.
